Co-founder is marriage without the sex.

[Matthew Prince 🌥 @eastdakota]

Welp, that happened faster than I predicted. Thought it would be end of 2027, then early 2027, but agentic traffic growing so fast that bots have now passed human traffic online for the first time in the Internet's history. https://t.co/2zX5bHdhsa

Building apps has never been easier.

With Sites, Codex can turn your work, ideas, and plans into an interactive website or app your team can explore, use, and share with a URL.

Rolling out to Business and Enterprise plans, before expanding more broadly.

[Claude @claudeai]

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors.

Available today at the same price.

One API for every frontier and open-weight model.
1000+ models. text, image, video, voice, music, 3D.

[Claude @claudeai]

Effective today, we are:

1) Doubling Claude Code’s 5-hour rate limits for Pro, Max, and Team plans;

2) Removing the peak hours limit reduction on Claude Code for Pro and Max plans; and

3) Substantially raising our API rate limits for Opus models.

[Claude @claudeai]

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.

This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.

[John Collison @collision]

At Stripe Sessions, we showed how we think agentic commerce will often happen behind the scenes in the course of producing other final products. Here, we show our Claude Code using MPP and @tempo to buy a dataset from @alpha_vantage in the process of generating a research report for me on AI energy usage.

[Rakesh Roushan @BuildWithRakesh]

Your AI agent just wrote a great promo email.

Then it dropped a 240-character UTM-stuffed raw URL into the CTA.

No tracking. No branding. No kill switch. No idea which run sent which click.

This isn't a marketing bug. It's a primitive that doesn't exist yet.

Web apps got `getServerSideProps`.
Payments got Stripe.
Transactional email got Resend.
Auth got Clerk.

The link an AI agent ships? Still a raw URL with a UTM glued on.

We're fixing that.

Today we're relaunching https://t.co/v0eu3qlKC3 as the link primitive your agent calls.

One line and any agent (Claude, Cursor, Codex, Mastra, Vercel AI SDK, your in-house copilot) can mint proper short links inside any workflow that contains a URL.

>> claude mcp add go2 -- npx -y go2-mcp-server@latest

That's it. No SDK. No webhook plumbing. No redirect service to maintain.

From that point, every link the agent creates is:

→ short + branded (your custom domain)
→ tracked (clicks, geos, devices, conversions)
→ attributed by run (agent_id, run_id, actor_id, tool_call_id)
→ lifecycle-aware (single-use, expiring, revocable)
→ owned by your workspace

Sub-10ms redirects at the edge.

Workflows this upgrades on day one:

- promo / discount emails
- drip + lifecycle sequences
- outbound prospecting
- support replies
- social + scheduled content
- internal Slack / Discord blasts

Anywhere an LLM emits a URL today.

Reply with the worst URL your agent has shipped this week. I'll quote-tweet the top three with the one-line install that would have fixed each one.

[Stripe @stripe]

Today, we’re launching the @link wallet for agents. It lets you securely empower agents to spend on your behalf. Your payment credentials are never exposed and you approve every purchase.

Signing up for Cloudflare in 2026...

[Patrick Collison @patrickc]

We just launched the @Link CLI: https://t.co/vYdvNtJgpE. Tell your friendly neighborhood agent about it -- agents can use the Link CLI to create single-use credentials that you get to synchronously approve each time.

I asked Claude to buy itself a gift. It chose HTTPZine on Gumroad.

[Cloudflare @Cloudflare]

Starting today, agents can now be Cloudflare customers. They can create a Cloudflare account, start a paid subscription, register a domain, and get back an API token to deploy code right away. https://t.co/qFgCivQTTi

CLAUDE OPUS 4.7 USING 500K TOKENS TO RENAME A VARIABLE

[Rakesh Roushan @BuildWithRakesh]

Alibaba submitted a video model pseudonymously to a public leaderboard.

It took #1. Then they claimed it.
HappyHorse 1.0 generates the audio in the same forward pass as the video. Dialogue, lip-sync, ambient. One model, one pass.

Under the hood:
– 15B params, 40-layer unified self-attention transformer
– Text/image/video/audio tokens in one sequence
– DMD-2 distillation, 8 steps, no CFG
– ~38s for 1080p on a single H100
– Closed-source, won't be open-weighted

Available now on AI/gateway. Same OpenAI-compatible API as everything else in the catalog. Change one model string, get video with synced speech.

OpenAI shipped two models in last 72 hours.

GPT-5.5: 82.7% Terminal-Bench. $5/M in, $30/M out.

GPT Image 2: 2K res, character-accurate Hindi/Arabic/Mandarin, $0.04–$0.35/image.

Both live on ai/gateway today. One key. One endpoint.

[Sam Altman @sama]

feels like a good time to seriously rethink how operating systems and user interfaces are designed

(also the internet; there should be a protocol that is equally usable by people and agents)

Open letter to Indians in America.
--
Dear brothers and sisters from Bharat:

Like I did 37 years ago, you arrived in America with no money but with a good education and cultural heritage from Bharat. You achieved outstanding success. America was good to us. For that we must remain grateful - gratitude is our Bharatiya way.

Yet today, a significant number of Americans, may be not the majority but not too far from it either, believe that Indians "take away" American jobs and our success in America was unfairly earned.

You may think the next election will fix this, but your choice would be between people who hate our Bharatiya civilisation and people who hate civilisation itself. That is the "hard right" vs "woke left" battle. You are mere bystanders to that conflict.

Meanwhile there is one thing that is true now and will be true in the future: the respect Indians command world-wide will substantially depend on the fortunes of India herself. If India remains poor, the woke left will give us moral lectures with pity and the hard right, different moral lectures with scorn ("hellhole") and we must not confuse either with respect.

Respect in today's world, along with prosperity and security, comes from one source: a nation's technological prowess. India produces sufficient brain power to achieve that prowess but alas we exported so much of that talent, particularly to America. As we develop that prowess in India, our civilisational strength will assert itself.

As difficult as it is for many of you to contemplate this, please come back home. Bharat Mata needs your talent. Our vast youthful population needs the technology leadership you gained over the years to guide them towards prosperity. Let's do it with a missionary zeal.

Respectfully
Sridhar Vembu
